Noxtua

Noxtua is a European legal AI platform for research, analysis, and drafting, built on curated content from European legal publishers and hosted on European infrastructure.

Law firms and in-house teams work through Projects for matter context, Workflows for recurring tasks, Matrix Analysis for turning large document sets into structured data, and add-ins for Microsoft Word and Outlook. It runs two agent tiers: Athena on open models on sovereign European infrastructure, and Minerva on international frontier models under European security controls.

Buyers compare it against Harvey on depth of German and Austrian sources, compliance with professional-secrecy obligations, and certifications including BSI C5, ISO 27001, and ISO 42001. CMS and Dentons remain anchor clients.

Noxtua AG is a Berlin legal-AI company, registered at the Charlottenburg commercial register under HRB 202784 B and led by Dr. Leif-Nissen Lundbæk as chairman of the executive board. It builds legal AI on curated content from European legal publishers, running on European infrastructure under BSI C5, ISO 27001, and ISO 42001 certification.

In September 2026 the company raised more than 100 million euros in a Series C that made C.H.BECK, the independent family-owned German legal publisher, its majority shareholder. Austrian legal publisher MANZ joined as a new investor, while Global Brain and the KDDI Open Innovation Fund exited. Ownership sits entirely with European publishers and investors.
